Hey TurboIndia can you give me some more info on above items? also your previous Turbo Honda city which you sold off did it had rear disc brakes?
& thanks for the contact info will call him up soon.

@ ~ HONDA ~ Thats a compliment for me ~ Thank you ~

& i want my braking to improve so i am looking for a simple, cheaper & cost effective solution.
I know some of Wildwood Brake Kits (slightly bigger Cross drilled Rotors, Calipers,Pads etc)that will Fit the Honda with minor alteration but they cost a bomb!

Yes my turbo honda did have disks at the rear.

I dont know anyone in mumbai who can source these for you.

We dont have Tarox rotors for the honda's as yet. We have only for the Skoda's & Fiesta and pads also for the Accent

That car's kit came from Thailand. I dont see that car regularly to take a snap of the brakes.

Turboindia,

How much of a difference do you feel the rear discs made on the OHC ?

A basic doubt... my apologies if I am missing something-

As per my knowledge, rear disks should not be really necessary. The reason is that most (60-90%) of the braking job is done by front wheels alone. First of all, front wheels carry more load (due to the engine). Additionally, as you brake a lot of weight gets transferred to front wheels, while further reducing the load on rear wheels. This makes rear wheels much more prone to locking (which may in turn result in fishtailing). In fact there is a safety feature called "proportioning valve" to apply only certain (lesser) percentage of brake force to rear wheels as compared to front ones to make braking more stable, even at high speeds. It is indeed a crude, fixed brake force distibution system in place! Therefore front disk- rear drum setup should be more than enough. It also makes the parking brake system easier. This is the reason why many cars use use this setup, not meerly for economy.

Considering above facts, why do we still need disks at rear? Are there any specific advantages? (especially for non-ABS cars)

Hi Santosh,

What you are referring to is Adjustable Brake Bias Valve which adjusts the braking pressure between front and rear brakes. These are mainly used/found in race cars or high performance sports cars. Almost all rally cars have this feature.

It is not required for the regular passenger cars and to answer your question YES disc brakes at the rear are far safer than the drum brakes.

Reduced brake fade, less braking effort, no need to adjust linings

Actually, Viper, some cars DO have this valve. The Safari definitely has an LSPV or load sensing proportioning valve, unless I'm mistaken. Not sure about the regular sedans we drive, though.

Is this adjustable brake bias valve a bolt-on mod? And where is it available?

My friend has disc brakes at the rear of his OHC and recently even bought some racing pads. I'll help u source them.
Meanwhile, speak with Das and let me know.

My car - baleno has this kind of valve. Though I don't know if it can change the proportion depending on loading or speed, amount of braking etc. Apart from improving actual braking forces, it also serves another purpose of accounting for different types of brakes in front and rear. The reason is that drum brakes are kind of "self actuating", they need relatively lesser force applied to its shoues than disk brakes. It is little difficult to find out which cars do have it and which don't, because it may or may not be advertised or included in "user" spec sheet.

linings adjustment part should not be applicable for "self adjusting" drum brakes. At least the baleno has it, too... no idea about OHC/NHC. Only thing is that you should check its health during servicing, otherwise it may gather dirt or rust and stop working!

I guess braking effort could be compensated by vaccume assist systems (and self adjusting mechanism as well). In fact drum brakes require lesser force as mentioned in the previous post, thats why it makes parking brake easier. Are you referring to additional distance that the pedal may have to travel in case of fadded shoues? I was wondering there must be something else also that makes disk brakes better than drums in general!

It is actually a pretty easy job if you have all the tools and the equipment with a mechanical inclination you can do it yr self

I dont think so....
If you think Rear Drums are better than Disc then please explain why do cars like Skoda, Accord and other cars in their segment have rear Disc....
